Title: Helical scan digital data VCR - monitors actual tape position and speed for use by processor to initiate changeover at correct point for playback at different speed
Inventor: FACH REINHARD
IPC: G11B15/18
Filed: 1992-12-02
Abstract: Digital information signals are recorded on angled tracks and read by a helical scan process in which the tape is passed around a rotary drum with a pair of heads. Control information is recorded along the edge of the tape. One of the drum heads is used for normal speed and one for a different speed. Changeover is provided by a circuit (2) that calculates and determines the point of generation of a changeover pulse (KU). A counter responds to tachogenerator pulses with a period defined by a reference (REF) pulse, produced once for each rotation of the drum. This is used together with the control track information (ST) to determine the precise point for changeover. ADVANTAGE - Head changeover is independent of amplitude variations of scanning signals delivered from heads.

Title: Plasma cutting burner for cutting metallic materials
Inventor: MADSEN HANS
IPC: H05H1/34
Filed: 1993-02-21
Abstract: The invention relates to an improvement in the thermal stability and cutting beam geometry of a nozzle system for plasma cutting of metallic materials, and to a plasma cutting burner of corresponding construction. It furthermore includes elements which prevent any hazard to the labour force resulting from the voltage applied to the burner electrodes. Such a plasma cutting burner consists of a cathode, which is composed of a cathode tube and of a replaceable cathode cap which has a cathode pin which is centred and on the nozzle side, having water cooling which is arranged inside this cathode and encloses it - the external diameter of the cathode cap being equal to the internal diameter of the lower insulating element enclosing it, spiral gas ducts being arranged in the casing of the cathode cap, which gas ducts originate from the annular gas space and end in a vortex chamber. There is a guide funnel in the nozzle cap, between the vortex chamber and the nozzle opening. The design of the internal space of the nozzle cap ensures that the plasma jet (plasma beam) is formed particularly exactly.

Title: Method for producing an ISFET with a back film (diaphragm)
Inventor: HOWITZ STEFFEN DR
IPC: G01N27/414
Filed: 1993-05-13
Abstract: The invention relates to a method for producing an ion-sensitive field-effect transistor (ISFET) in which chemically sensitive films, which are buried by the use of the implantation technique, and simultaneously constitute an insulator layer of the ISFET structure, are produced without additional layer deposition procedures. According to the invention, this is done by bombarding a (100) p-silicon single crystal in staggered fashion in the energy range of 300 keV up to a few MeV with N+ and O+ ions and subsequently exposing it to defined annealing and diffusion processes. This produces layer definition of the stack insulator in the silicon substrate, layer and structure definition within the SiO2-Six-OxNz-Si2N3 insulator stack and the ideal formation of the electronic interfaces between the monocrystalline (100) p-Si top layer and the insulator stack. After this insulator burying, the complete ISFET preparation is carried out in the monocrystalline Si top layer. The chemically sensitive film is uncovered in the last step by simultaneous anisotropic etching in the full wafer process, the Si3N4 film layer acts in this case as an ideal etching barrier layer, and the component is immediately useable.

Title: Automatically controlled machining device for spectacle lens edge
IPC: B24B9/14
Filed: 1993-05-26
Abstract: The machining device has at least one tool engaging the circumferential edge of the spectacle lens supported in a clamp which rotates the lens about an axis of rotation perpendicular to the lens apex. The distance between the tool holder for the machining tool and the clamp is controlled automatically in dependence on the angle of rotation of the clamp about the rotation axis.A sensor unit has at least one sensor detecting the distance of the adjacent edge from the rotation axis as a function of the rotation angle, to provide as actual value compared with a required value by the control unit to adjust the advance. The lens clamp or the tool holder is moved during machining and/or prior to fine polishing, so that the sensor cooperates with the immediately processed lens edge.

Title: Circuit arrangement for a digital phase comparator
Inventor: RIEDER KLAUS-HARTWIG
IPC: H03L7/085
Filed: 1993-10-23
Abstract: A digital phase comparator is a component of a clock generator in a phase-locking loop and is used for frequency and phase comparison between a reference clock and an oscillator clock. The object of the invention is to specify a phase comparator which can be produced simply with digital circuits and allows high phase resolution, with high linearity, over a large measurement range. In order to achieve the object, functions and components, which in any case are carried out or are present, respectively, in a digital phase-locking loop, are used for measuring the phase difference. According to the invention, the circuit arrangement consists of a counter (51) clocked by the oscillator (1), the count result of which is fed in the clock-pulse of the reference frequency to a register (21), at the output of which a digital value is provided as a measure of the phase difference. Since the counter (51) is usually a component of a digital phase-locking loop, only a register (21) of simple design is required in the present case, instead of a known phase comparator. The resolution of the phase comparator can be increased by raising the clock frequency, and the measurement range can be increased by spreading the data signal of the counter (51). <IMAGE>

Title: Gelatinous material for the percutaneous administration in particular of medicaments
Inventor: ANZ JOHANNES DIPL ING
IPC: C08F265/02
Filed: 1993-10-25
Abstract: The invention relates to a gelatinous material based on acrylic acid for the administration in particular of medicaments through the skin of a mammal, especially humans. Known gelatinous materials of this type have only a low material thickness, therefore have only a low absorption capacity and are limited in their use to only a few active ingredients. In addition, their preparation is very elaborate and costly, and the polymerisation can be carried out only under an inert gas. In order to eliminate these disadvantages, a gelatinous material which comprises of a reaction mixture which is polymerised in situ with UV light under standard conditions and comprises ethylenically unsaturated monomers based on acrylic acid which are dissolved in an aqueous polyol-containing liquid, is proposed. The gelatinous material contains further additives such as initiators, coinitiators, crosslinkers and polyacrylic acid.
